BROW LANTERN AND REFLECTORSUPPORT WITH UNIVERSALLY ADJUSTABLE BASE Filed July 18, 1949 o 2Sheets-Sheet 2 Patented July 3, 1951 NITED STATES PATENT OFFICE LANTERNAND REFLECTOR SUPPORT WITH UNIVERSALLY ADJUSTABLE BASE This inventionrelates to certain new and useful improvements in a lantern hood orguard and reflector.

The primary object of the invention is to provide a lantern hood orguard and reflector designed for many uses, one of which uses is hereinillustrated as being in connection with a ship or boat with the hood orguard mounted on the gunwale of the boat.

A further object of the invention is to provide a lantern hood or guardof the foregoing character constructed for free rotary adjustmentwhereby light rays from the lamp may be directed in the desireddirection, with the mounting elements for the hood or guard providingfor angular adjustments in vertical directions.

A still further object of the invention is to provide a bracket mountingfor the lantern hood or guard whereby the clamping elements of a bracketmay be either vertically or horizontally positioned for engagement withan appropriate support.

It is a still further object of the invention to provide a lantern hoodor guard in which the wall thereof that is of substantially cylindricalconstruction is formed of overlapping sections that may be verticallyadjusted to accommodate lamps of different heights.

With the above and other objects in view that will become apparent asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawings, and claimed.

Figure 11 is a detailed sectional view taken on line ll ll of Figure 10,and

Figure 12 is a fragmentary plan view of the perforated head portion ofthe hood or guard.

Referring more in detail to the accompanying drawings, there isillustrated a lantern hood or guard and reflector that comprises asupporting frame designated in general by thereference character l5, alantern hood or guard mounted thereon and generally indicated at Iii,while the lantern mounted within the hood or guard is shown at IT.

The supporting frame, as shown most clearly in Figures 2, 4, and 6,comprises a ring l8 having a section 19 thereof set in a plane below theplane of the other section 20 for purposes presently to appear. Crossedreinforcing spider arms 2i and 22 are connected at their outer ends tothe ring and their crossing points form a hub 23. The spider arm 22adjacent the ring. section 20 carries an upwardly and angularly directedarm i l for the pivotal mounting of a vise-like clamp that has a bar 25carrying depending end lugs 26 and 21 adapted to straddle a support 28such as a gunwale or the like with r the leg 26 engaged'with one side ofthe gunwale.

Aclamping screw 29 threaded through the other leg 2'! engages the otherside of the gunwale for the rigid mounting of the supporting frame. Anarm 3!] extends from the end of the bar 25 for pivotal mounting as at 3|to the upper end of the: arm 24 as shown in Figures 2 and 6.

The lantern hood or guardincludes a base plate-32 of disk form and'aheaded bolt tspasses centrally downwardly through the base plate 3 2 andthe-hub 230i the: spider arms forthe' reand 2. through the rear side ofthe wall 49 of the lan- 3 ception of lock nuts 34 on the lower endthereof, washers or gaskets 35 being interposed between the base plate32 and hub 23 whereby the disk plate is freely rotatably mounted on thesupporting frame. A plate upon which the lantern i7 is fixedly mountedis indicated by the reference character 36 and is supported on the baseplate 32, the bolt 33 passing centrally therethrough, while said pate 36is anchored at suitably spaced points by screws or the like 3'! passingtherethrough and entering the base plate 32 as shown in Figure 6.

A split clamping ring 38 surrounds the plate 3t and extends thereaboveas illustrated for engagement with a base flange on the lantern I? andsaid split ring is then secured together at its split ends by lug andbolt combinations 3% as shown in Figures 1 and 3.

The hood or guard It for the lantern is secured to the base plate 32 andincludes a vertically semi-cylindrical wall 3% surrounding the baseplate at its lower end and anchored thereto as at Ill. An arched hood 42is secured to the upper end of the wall t!) and has a lip extension 43at its upper end that overlies the upper end of the cap as of thelantern l? as shown in Figure 5. A lifting handle 45 for the guard orhood has one end leg es thereof anchored to the hood 42 in proximity ofthe lower rear edge thereof, while the other end leg 4'? of the handleextends over the lip 53 on the hood (52 with a threaded bolt 53 passedupwardly through the lantern cap 4! lip 43, handle leg Ail for thereception of a retaining nut 4;). The reference character 553 designatesa hinge-d bail secured to the lantern as shown in Figures 1 Access maybe had to the latern li tern hood or guard by the provision of anopening in the lower end of the wall ll] that is normally closed by acover 52 hinged to the wall as at 53. a

When it is desired to rotatably adjust the 'hood it that is fixed to thebase plate 32, the latter may be readily grasped at its forward sidewhich is made possible by the lowering of the section IQ of the ring ofthe supporting frame. It will also be observed that the upper section 20of the ring it has an upset portion 2?? to provide a clearance formovement of the bar 25 of the bracket clamp. Also, the bar 25 of thebracket clamp carries a transversely exescape of heat rising from thelantern.

In lieu of the ring l8 and its four spider arms 2| and 22, a skeletonframe may be substituted as shown in Figure 1 wherein the central hub 23has two arms Zi and one arm 22 radiating therefrom, the arm 22* carryingat its outer end a block enlargement 56 on which the clamp arm 36 may bepivotally mounted.

The spilt clamping ring 38, as shown in Figure 6, for anchoring thelantern I! in position may be eliminated and the plate 36 shown inFigure 8 may have radial slots 51 therein for the slidable mounting ofadjustable clamps 53 that engage the base of the lantern as will be 4understood from an inspection of said Figure 8 and also Figure 9.

The lantern hood or guard I6 is shown in Figures 1, 2, and 6 ascomprising a single semicylindrical wall 4%, but in Figures 10 and 11 amodification of the hood or guard is shown and it comprises upper andlower semi-cylindrical wall sections 69* and flil that are assembled invertically telescoping relation with interfitting beaded edges as shownin Figure 11 that are held in adjusted position by the set screws 6Bassociated with said beaded edges. An extensible structure of thischaracter will accommodate a lantern of difierent heights.

From the above detailed description of the invention, it is believedthat the construction and operation thereof will at once be apparent, itbeing noted that the supporting frame It forming the base structure ofthe hood or guard may be mounted on the gunwale of a boat as illustratedin Figures 2 and 6, or the supporting frame may be mounted on a fiattable support or the like upon laterally shifting the U-shaped vise-likeclamp comprising the bar 25 and lugs 26 and 2?. Rotary adjustment of thehood or guard is facilitated by its axial rotation on the vertical pin33 so that light rays may be cast in the desired direction.

While there are herein shown and described the preferred embodiments ofthe invention, it is nevertheless to be understood that minor changesmay be made therein, such as will fall within the scope of the inventionas claimed.
